PRTG API and set-channelprotperty -lowererrorlimit #291

Open carsten0407 opened 2 years ago

What's going on?

Hi Comunity,

at one PRTG-Server we have the problem, when we configure the thressholds through PRTG-API with

get-probe -name customer | get-sensor -id 5358 | Get-Channel -id 0 | Set-ChannelProperty -LowerErrorLimit 50000

The result looks like

05-07-_2022_10-07-58

Must be a problem on that PRTG-Server. On the other 4 PRTG-Server the problem not exist!

Any Idea?

Due Dilligance

lordmilko commented 2 years ago

Can you please provide the output of Get-PrtgClient -Diagnostic

Can you do Set-PrtgClient -LogLevel All and then provide the output of

get-probe -name customer | get-sensor -id 5358 | Get-Channel -id 0 -Verbose | Set-ChannelProperty -LowerErrorLimit 50000 -Verbose

Please omit the servername, username and passhash from the response

Hi Lord,hope this is enoung

carsten0407 commented 2 years ago

too much output here, how can I redirect in a file?

lordmilko commented 2 years ago

This is the output of Get-Channel with -Verbose, however I do not see the output of Set-ChannelProperty with -Verbose here

carsten0407 commented 2 years ago

I have the dump, it's big but unfortunately with a lot of customer information.

carsten0407 commented 2 years ago

can I share it to you with privacy

lordmilko commented 2 years ago

From Set-ChannelProperty I just need the API URLs that were executed

If you do Set-PrtgClient -LogLevel Request and do Set-ChannelProperty with -Verbose again this will just give you the API calls that were executed. There shouldn't be any sensitive customer information in these

lordmilko commented 2 years ago

get-probe -name customer | get-sensor -id 5358 | Get-Channel -id 0 | Set-ChannelProperty -LowerErrorLimit 50000 -Verbose

Black-Pawn-C7 commented 2 years ago

This is not a Problem with PrtgAPI but rather a conversion error. You are setting the LowerErrorLimit to 50000 Byte not to 50000 MB. To be more specific 50000 Byte = 0.04768372 MiB which is exactly the value being displayed. Use 52428800000 instead of 50000 and your script will work

lordmilko commented 2 years ago

When you tell PRTG to display figures in megabytes, or any other unit, it is possible to say "50000" in the user interface, which will correctly be interpreted as 50,000 megabytes, not 50,000 bytes

The way this works is that a unit "factor" is submitted along with the API request that tells it how to correctly process the number you submitted

The following shows the API request that is made when setting a channel on a WMI Free Disk Space sensor on my system

C:\> get-device ci*|get-sensor "*disk free*"|get-channel total|Set-ChannelProperty -UpperErrorLimit 1000 -verbose

http://prtg.example.com/editsettings?id=2061&limitmaxerror_-1=1000&limitmode_-1=1&limitmaxerror_-1_factor=9.5367431640625E-07&username=prtgadmin&passhash=****

The limitmaxerror_-1_factor field tells PRTG that the value I submitted - 1000, is a value in megabytes, not bytes. When I check the web UI, I confirm I get the value 1000 as expected

image

If this is not working as expected, this implies there is an issue with how PrtgAPI selects the factor to include in the request (there are actual several factors returned, and I simply assume they're all always the same). Hence I need to see both the full requests and responses that are made when this is not working

Okay, this makes sense and has also worked in our environment. However, it is still inexplicable. When we execute the command on a German server with a German OS, the output works without any issues; it enters the 5000MB. On an English OS, we get 0.04768372. Conversely, this happens with a server with an English ISE, and it works seamlessly on all English servers but not on the German one. It's complex and difficult to explain, I know. In summary, it must be a language-related issue, but which one? Everything was working fine until last week.

It's possible this has to do with how some regions use a period for denoting a decimal place, while others use a comma. What PrtgAPI will send in some circumstances can depend on your client operating system region settings, and what PRTG may require in some circumstances may depend on the PRTG server's operating system region settings
